Title: Improvements relating to multiple passage valves
IPC: F16K11/074
Filed: 1933-11-02
Abstract: 427,971. Softening water; filters. UNITED WATER SOFTENERS, Ltd., Aldwych House, Aldwych, and INCH, A. C., Permutit House, Gunnersbury Avenue, Chiswick, both in London. Nov. 2, 1933, No. 30511. [Class 46] [See also Group XXIX] A multiple-way rotary disc valve for a base-exchange plant or a filter plant has the disc 5 mounted in a cavity in a stationary housing 1 to which all the necessary pipes for the plant are connected, a non-rotatable ported or grooved member 7 being mounted in the cavity and loaded so as to press only on the valve disc the ported or grooved faces of which are maintained in liquid-tight contact with seatings in the housing and on the non- rotatable member. The housing casting 1 is screwed to a ring 2 on a container 3 for watersoftening material. The disc 5 has hard rubber or ebonite faces 9, 10 pinned to it and an integral spindle 11 to which is secured a hand wheel 12 carrying indices movable with respect to a fixed pointer 28 to indicate the operation in process in the apparatus. The ported plate 7 which is provided with two eccentric apertures is pressed against the valve 5 by a spring 6 arranged about a pipe 21 extending to the bottom of the container 3. Studs 8 prevent the plate 7 from rotating. Passages 13, 14, 15, 16, Fig. 2, in the casting 1 all leading to the end wall of the cavity 4 are connected respectively to a source of hard water, a soft water service pipe, a tank of regenerating brine, and to waste. In normal service, the hard water from the passage 13 passes through aligned ports in the members 1, 5, 7 to the container 3, and the softened water passes up through pipe 21 and passage 25 to the passage 14. The regenerating tank may be charged by connecting passages 13, 15 by means of lateral extensions of the port 23, formed in the face 9. Backflushing is then carried out by turning the valve so that hard water from the passage 13 passes through the passage 25 to the pipe 21, up through the water softening material, and through the valve again to the waste passage 16. The valve is then turned so that hard water flows from the passage 31, Fig. 5, into the nozzle 33, drawing with it regenerating liquid through the passage 34. A final rinsing phase is obtained by turning the valve slightly so that the passage 34 is cut off from the supply of regenerating liquid. A bore 36, which is normally closed, is used for cleaning the passage 31 and nozzle 33. A throttling screw is provided in the passage leading to waste.

In a fluid pressure braking system comprising at least one brake cylinder 14, a source of fluid pressure 2 and a unit 4 including a driver actuated slide valve 6 disposed between source and cylinder, the slide valve coacts with a piston 9 housed in a chamber 8 to form a device for damping out the vibrations of the slide valve and the brake cylinder is connected through an auxiliary pipe line 21 to the chamber 8. On actuation of the valve the pressure in the cylinder 14 acts on the piston 9, which has ample clearance in the chamber 8, to provide an upward force on the valve 6 and oppose, together with the force of spring 7, the application force on the pedal 24. On release of the pedal force the former forces raise the valve 6 to connect the brake cylinder with the reservoir line 2 through passages 13, 23, 5 and 21, 22, 23, 5. The latter route provides an arrangement for automatically bleeding the system. The valve 6 may be actuated directly by the driver. Alternatively, two slide valves 6 may be provided and controlled by a compensator lever.

Title: Fibre fleeces and synthetic leathers
IPC: D04H1/4258
Filed: 1971-07-07
Abstract: 1354746 Non-woven fabrics BAYER AG 7 July 1971 [11 July 1970] 31827/71 Heading D1R [Also in Division B2] A filter or artificial leather is produced by treating an unbonded fleece with a pre-mixed, reacting solution of a compound containing NCO groups plus a compound containing NH groups and/or a compound containing OH groups which yields 10 to 500% by weight of the fibres of a microporous polyurethane or polyurea which is insoluble in the solvent for the reactants, completing the reaction and simultaneously or subsequently removing the solvent by evaporation at a temperature below its boiling point. One or both sides may have a microporous, otherwise continuous surface layer of polyurethane. The fleece may be carded, air laid, spun bonded or wet laid, it may be stitched, and comprise polyester, polyamide polyacrylonitrile. polyvinyl chloride, polyvinyl acetate, polyvinyl alcohol, cotton, rayon, collagen or polyurethane fibres, or mixtures thereof. If the fleece contains smellable fibres it is wet with solvent before it is processed. The solution of reactants must be sufficiently concentrated for the polyurethane formed to enclose the solvent that has not evaporated during the reaction, so that the solvent leaves the polyurethane phases as dispersed pore-forming droplets and not as a continuous supernatant phase. In example 5 the polyurethane is prepared in a one stage process by stirring 30 gms of a partly branched polyethylene glycol adipate and 4.8 g di-(#-hydroxyethoxy)-benzene-(1,4), in xylene/dimethylformamide at 100‹C, adding 11 g 4,4'-diisocyanato-diphenylmethane and 0.1 g diazabicylooctane and stirring for 8 seconds. The mixture is poured over a polyethylene terephthalate fleece so that 2 mm. of solution stood over the surface of the fleece. In example 4 the above reacting mixture may be poured onto a hot glass plate. After 240 seconds a needled fleece of 70% polyamide, 20% bicomponent polyamide and 10% vinyl chloride/vinyl acetate copolymer adhesive fibres was placed on the coated glass plate and coated with similar solution. After the reaction has terminated and the solvent removed the product is split to give two fabrics each coated on one side. Example 2 describes treating a polyamide fleece with a similar reaction mixture, heating in ovens to complete the reaction and dry the product being specified.  In example 3 a 2-stage polyurethane preparation comprised adding 2.4 g 2, 4 diaminotoluene in dioxane to 50 gm of a prepolymer from 500 g polypropylene glycol ether (OH number 56) and 125 g 4,4'-diisocyanato-diphenylmethane (2.8% NCO) in paraffin at 100‹C. After 3 seconds stirring the reacting solution was poured onto a 55% polyamide, 40% polyacrylonitrile and 5% regenerated cellulose fleece which was squeezed lightly with a glass rod and dried at 100‹C. The use of other 2 stage polyurethane preparations to bond and coat fleeces is described in examples 1 and 6. The Specification lists possible reactants and solvents, and specifies the water permeability and other physical properties of the products.
